9 Ways To Fix SmartCast TV Not Available Issue(+Reasons)

Casting is a great way to get content from a wide range of devices to your television without having to rely on a suite of apps that may not always work correctly and don’t always get updated when they should.

How to fix your SmartCast TV when it says it’s not available/working? Power cycle the TV. Unplug your TV from the wall, wait 1 minute, plug it back in. Restart/reinstall your casting app. Turn your casing device off/on. Reboot your router. A combination of these steps should solve the issue.

For many, however, the most cost-effective method to get casting capabilities to your television is to add a Google Chromecast- an inexpensive dongle that plugs directly into your TV’s HDMI slot and takes care of the casting for you.

It is a good solution, and given that Google’s casting technology is one of the leaders in this space, it makes sense that Chromecast would be one of the more reliable options. Check out the list of the best streaming devices on Amazon now!

What is “Casting”?

If all of this talk of casting is leaving you a little confused, don’t worry; here’s a crash course in what casting is in this context.

Casting is the process of sending video from one device to an external display, allowing you to essentially use that device as a remote control for your display since you can play, stop, skip, and all the other controls you might want when watching video content.

The smart thing about Google’s casting technology-and as a result, Vizio’s SmartCast technology-is that when you cast video, the video is not being streamed from your device to your TV, but directly from the Internet.

In effect, you are using your device purely as a controller. This allows you to add a range of video sources to your television, such as Netflix, Disney+, Amazon Prime, etc., without ever installing a single app on your TV or buying an external streaming device like an Apple TV or Amazon Firestick, but without losing the smooth, high-speed experience that streaming directly grants you. If you want to connect your laptop to your Vizio TV wirelessly, use these tips.

Reasons SmartCast Doesn’t Work on Your Vizio

There are several reasons why SmartCast might have stopped working on your Vizio TV, so let’s tackle them one at a time, starting with the most obvious. If it was working and suddenly stopped, it is highly likely that something as simple as a power cycling of your router could fix the problem.

If this is the first time you have set your SmartCast TV up and you cannot get it working, you will have to look at all eventualities to find the culprit.

No Internet

It may sound obvious, but you might be surprised at how many people don’t think to check their Internet connection when they encounter problems like this.

The content you are trying to watch is being sourced by your device and delivered to your TV directly, so if there are problems with your Internet connection, your SmartCast functionality will not work correctly.

There can be confusion around this point, specifically over the fact that you can have your SmartCast TV not working properly while you are still able to reach Netflix or YouTube or whatever streaming service you are attempting to cast from your phone.

Remember, your phone has a data connection with your cell provider, and will likely switch to that if your home network drops out. That means your phone could still be accessing the Internet while your TV cannot. And, on a related note:

TV on a Different Network

In order to cast to your TV, the device you are casting from and your TV must be on the same local network. If your TV is connected to your home WiFi, but your phone is using data-or you are attempting to cast from a computer that is on a different home network to your TV-it won’t work.

App Does Not Support Casting

The nature of casting, as we described above, means that the content you are attempting to cast needs to come from a service or app that supports casting.

Of course, casting has become incredibly popular, and there is a huge number of apps and services that support it, but if you can’t figure out why your SmartCast TV isn’t working, it might be worth making sure it is supported.

Router Issues

Your router is responsible for bringing an Internet connection into your home and distributing it among all of the different devices. Like many things in the world of technology, it can sometimes get a little befuddled and not behave the way it should.

Ways to Fix SmartCast TV Not Available/Working Problem

Of course, knowing what might be causing your problem is little solace if you can’t fix it. Don’t worry; we’re not going to leave you high and dry. Here are some things you can try to get your SmartCast TV behaving the way it should. 

1. Try Another Network

If possible, try connecting your TV and casting device to another network to rule out anything to do with that side of things. It will help to understand if your ISP is causing the error or not.

  1. Connect your TV to another network/mobile phone’s hotspot
  2. Now see if there is any difference in your TV functionality

2. Make Sure Your Internet Connection is Working

We mentioned it above, but it deserves a second mention because this really is the most common cause of this kind of problem. If your Internet is down, you will need to remedy that first. This may mean contacting your Internet service provider and having them sort things out. Try changing the position of your router, it might be too far away to provide a good signal,  or bypassing the router and connecting your SmartCast TV directly to the modem.

3. Refresh SmartCast Home

Sometimes a simple software glitch can be an issue, this method is pretty good at rolling out this issue:

  • Switch your TV to the SmartCast Input.
  • Open your TV Menu
  • Navigate to the System Menu.
  • Change the Language to Spanish/French Don’t close the menu.
  • Wait for SmartCast Home to Load. If SmartCast Home does not load the issue is likely to be with your home Network being slow, which we discussed earlier.
  • After SmartCast Home Loads, change the Menu language back to English.

4. Reinstall the Casting App

Sometimes your TV might be not the one to blame. In this simple step, first, try to turn your device on and off, and then, if that doesn’t work, uninstall the app, reinstall it again and try to pair it with your TV.

5. Change Your DHCP Setting

Next, let’s try to change the DHCP setting of your network, this way different IP addresses will be assigned to all of your devices, this is likely to stop the error from occurring.

  • Turn off your SmartCast TV
  • Open your computer, use any browser and type your router’s URL
  • Enter your username and password
  • Go to the SettingsAdvanced/Network SettingsDHCP Setting
  • Enable the DHCP Setting
  •  If previously enabled ⇒ disable it ⇒ enabled again
  • Click Save and Close the Settings page
  • Turn on your TV
  • See if it helped

6. Try to Power Cycle

If turning your TV, router, and casting device on and off did not work for some reason, let’s try to power cycle. If the problem with your SmartCast is some sort of a software hiccup, that should do the trick. Power cycling will help to erase all the temporary configurations and then reconfigure them once you turn the device back on.

  1. Press the Menu button and select System on your TV remote control
  2. Select Reset and Admin
  3. Select the Soft Power Cycle
  4. While doing that, power off your router
  5. Turn the power on and check if the TV is working fine

7. Update Your TV’s Software

It is always a good idea to check from time to time if there are any new updates available for your TV that you might have missed. In this step, we are going to try just that. Hopefully, it will stop the error from happening.

  • Go to SettingsSystems System Updates
  • See if there are any updates available
  • Install the updates
  • Wait for the TV to restart

8. Reboot Your Devices

It’s something of a cliche, we know, but it’s a cliche for a reason. Turning technology on and off works surprisingly often, and this goes for just about anything with a computer inside of it. The first place to start would be your router since that is most often the culprit. If rebooting doesn’t do the trick, try the same with your TV, and finally, the device you are casting from.

First, try to reboot:

  1. Your router
  2. Your TV
  3. Your casting device

If that did not work, try doing the following:

  1. Power off your TV
  2. Unplug your TV from the socket
  3. Hold the power button of the TV for about 20 seconds with the TV still unplugged
  4. Plug the TV back in
  5. Repeat step 3
  6. Power on your TV
  7. See if the problem persists, this way should help

9. Try to Factory Reset your TV

This method can also help with some possible glitches that your TV might have, thus helping with the SmartCast issues. All Vizio TV’s vary, but here are the most general guidelines:

  1. Press the Menu button and then System on your remote
  2. Open Reset and Admin
  3. Select Reset TV to Factory Settings
  4. Wait for the TV to reset itself.

If you want to factory reset using your remote, simultaneously press and hold both the Input and Volume Down buttons for at least 5 seconds until a bar ops up on your TV. Then press and hold the Input button again for at least 5 seconds until your TV screen turns itself off. Turn your TV on and follow the reset instructions.
